13 Claims.

My invention relates to self-feeding mechanisms for baling presses, andthe main object thereof is to provide an intermittently driven feedconveyor upon which the material to be baled may be placed, and whichfunctions to deliver the material into the baling chamber of the balingpress in separate charges.

An important object of my invention is to pro- .vide an intermittentdrive for the feed conveyor wherein the advance of the conveyor is timedrelative to the feeder head of the baling press so that a charge of hayis delivered into the baling chamber each time the feeder head israised.

Another object of my invention is to provide a control means, positionedwithin reach of the operator, to regulate the amount of advance of thefeed conveyor so as to vary the amount of material delivered in eachcharge.

Another object of my invention is to provide a means, adapted to becontrolled by the operator, by which the feed conveyor may be stopped atwill to enable the operator to insert a division block.

A further object of my invention is to provide an improved means 'foradjustably supporting the outer end of the feed conveyor whereby it maybe easily and expeditiously raised or lowered to the desired elevationfor loading.

Mechanism 35 includes a frame havingspaced parallel frame bars 35. An endless feed conveyor 46 is supportedbetween bars Stand comprises a pair of spaced parallel endless chains 37connected by trans- V verse slats 38 equidistantly spaced along thechain. A pair of endless ropes or cables 39 are secured to the innerside of slats 38 and prevent the hay from falling through between theslats.

Transverse shafts 4i and 42 are provided at the inner and outer ends,respectively, of the conveyor frame and are journaled in bearingbrackets 43 secured to the bars 36; A pair of sprockets 44 are securedon each of the shafts 4! and 42 over which chains 37 are trained. Theinner end of mechanism 35 is supported on the baling press by means of apair of brackets 45 which are secured to the upper angle iron bar 2!.Brackets 45 are provided with perforations adjacent their outer ends toreceive shaft ii.

The outer end of mechanism 35 is supported by means of two adjustablesupports 41, best shown in Figure 3, extending between and havingpivotal connection with bars 35' of the conveyor frame and bar 22 of thebaling frame.

Conveyor 40 is advanced when drum BI is rotated in a' clockwisedirection, looking at Figure 3, through a ratchet mechanism comprising aratchet toothed member if formed integral with the inner end of drum 6!,and a companion toothed member 12 formed integral with a member i3slidably mounted on akey 69 provided on shaft 4!. A shifting fork 74engages in a groove in member 73 and is connected by a rod '15 with alever 16 mounted at the operators station, whereby the operator mayshift member l3 out of en- When member 13 is shifted into engagementwith member H, it frequently'happens thatthe teeth are not in positionto mesh but contact on their points. To prevent breakage to the teeth aspring Tl is mounted on the extended end of shaft 4i between the end ofdrum 6! and a washer to permit drum 6! to move outwardly against thetension of spring Ti. The inward movement of drum BI is limited by thedrum contacting the end of key 59, as shown in Figure 6.

The amount of hay delivered to the 'b'aling chamber in each charge isdetermined by the ex tent of movement of the conveyor 40 which de.

pends on the length of cable withdrawn from drum 6% at each stroke ofbeam 64. Beam 64 is slidable in bracket 65 and may be adjusted in- 'in arelatively short path and draw a small amount of cable 62a offdrum Bl,thereby moving conveyor 69 a lesser amount. In order that cable 62a willfeed on to drum 6| in aneven manner in all positions of beam 54', aguide bracket 18 is provided having'a pair of rollers 79 mounted on therear end thereof and spaced apart to receive a cable 620. therebetween.

The walking beam d ljmay be shifted to any desired position in bracket$5 by the operator from his station beside the ba ling chamber. Forthis. purpose an adjusting mechanism is provided comprising an adjustingarm 8| which ex- 2 tends upwardly from a pivotal connection with framebar. 22. The upper end fil'of arm 8] is arcuate and is disposedbetween'a pair of rollers '32 mounted on the forward end of beam 64. Thearm 8! is rocked about its pivot by means of a shifting bar 83 whichextends between arm 8! and a lever 84, Lever'84 is mounted on frame bar2! adjacent the operators station. Changing the position of lever 84rocks arm 81 which in turn shifts beam (i4 relative to bracket 55. Thedistance between rollers 8.2 is slightly greater than the width of theupper end 8! of arm 8| to prevent binding; The curvature of the upperend at of arm 8! is such that the center of curvature thereof concentricofthe axis of shaft 2'. when beam 54 is in mid position of adjustment.By. giving the upper end 8! this 7 curvatura beam Sa is heldsubstantially stationarywith respect 'to bracket 55 as the bracket andon shaft 21.

beam'are oscillated in all positions of adjusting arm 8|.

A modified form of intermittent driving mechanism for the conveyor isshown in Figures 7 to '12 inclusive. This modified construction includesa driving arm 9| supported from the conveyor frame for oscillatingmovement by a pair of links 92 and 93. These links are connected to aplate 94 secured to the adjacent frame bar 36 of the conveyor frame.Links 92 and 93 are of the proper length and so arranged that the lowerend of arm 9| moves in a substantially straight line. The link 92 ispivotally connected to the upper end of arm SI and extends substantially horizontal to a pivot bolt 95 located adjacent the inner edgeof plate 94. The link 93 is mounted on pivot bolt 96 provided on arm 9|,below the upper end thereof, and extends inwardly to a connection withpivot bolt 91 provided in plate 94, being substantially vertical whenarm 9| is in a mid position of its stroke.

When arm 9| swings inwardly, the lower end thereof engages a link of theadjacent chain 31 and serves to advance conveyor 40. The driving arm 9|is oscillated by means of a driving connection with rock shaft 21. Thisdriving connection comprises a cable |0I connected to bolt 96 on arm 9|and extending inwardly therefrom over a pulley I02 to a connection withan actuating member in the form of an arm I03 secured The pulley I02 issupported in a U-shapedbracket I04 secured to plate 94 adjacent theinner edge thereof.

The arm 9| is oscillated inwardly in an operating or driving stroke whenshaft 21 is rocked clockwise by reason of cable I 0| and is swungoutwardly in an inoperative stroke, when shaft 21 is rockedcounter-clockwise, by means of a spring I06. The spring I06 is anchoredto a bar 101 of the conveyor frame and is connected by means of a chainI08 with pivot bolt 96.

A driving dog I09 is pivotally attached, intermediate its ends, to thelower end of arm 9| and is adapted to engage in a link of the adjacentchain 31 of conveyor 40 when arm 9| is oscillated inwardly. The dog I09is yieldingly held in alignment with arm 9| by means of a spring IIOwhich extends between the upper end of dog I09 and pivot bolt 96. A stopin the form of a pin III is provided on arm 9| to limit the pivotalmovement of dog I09 when arm 9| is oscillated in the driving stroke,through the agency of which inward movement is transmitted from the armto the conveyor. When arm 9| is oscillated in its inoperative stroke thedog I09 pivots away from stop III, against the tension of spring H0, andrides over the top of the links of chain 31.

The driving arm 9| is held in alignment with chain 31 by means of aguide bar 2 secured on'plate 94. A stop H3 is provided on the outer endof bar 2 and serves to limit the outward swinging of arm 9|.

The amount of hay delivered in each charge is controlled by the amountof advance-of conveyor 40. The amount of advance of conveyor 49 isregulated by connecting cable |0I in the desired one of a series ofholes 4 in arm I03.

To enable the operator 'to stop the conveyor at will, a latch mechanismII6 has been provided by which the driving arm 9| may be locked out ofdriving engagement with chain 31. The latch mechanism H6 is mountedonplate 94 and comprises a latch member III pivotally supported at one endin a bracket 8 secured onthe outer face of plate 94. A latch finger I I9is provided on the free end of member I I1 and is adapted to extendthrough a slot I20 in plate 94, under the control of a manually operatedshifting rod I23, and engage arm 9| to lock it against swinging. InFigure 12 arm 9| is shown locked against swinging movement. A beveledsurface I2| is formed on the end of finger 9 to permit driving arm 9| toswing past finger II 9 in driving stroke, the return of the armthereafter being prevented by the engagement of the arm with the end ofthe latch member. A leaf spring I22 secured on bracket 8 is provided,which engages member I I1, and is tensioned to urge the finger 9 intothe slot I20. During operation, member H1 is held in the position shownin Figure 11, with finger I|9 withdrawn from the slot by shifting rodI23. Shifting rod I 23 is supported in brackets I25 secured to plate 94at each side of latch member H1, and is provided with. an offset portionI24 which is adapted to engage member 1 and rotate it toits unlockedposition when rod I23 is rotated. The latch member III is held in itsunlocked position by a laterally bent extension I28 on the upper end ofrod I23 which contacts the side of plate 94 when rod I23 is rotated to apoint where offset portion I24 is slightly beyond a dead centerposition.

The rod I23'is actuated Icy-means of a lever controlled from theoperators station. This lever comprises a bar I30 having a handle 'I3'Iformed on its rearward end and supported on frame bars 36. A hole isprovided in the forward end of bar I39 to receive an eye I32 formed onthe lower end of rod I23.

While I have described, in connection with the accompanying drawings,the specific form in which I prefer to embody my invention, it is to beunderstood that the invention is not to be limited to the specific meanswhich I have herein shown and described, and that, in fact, widelydifferent means may be employed in the practice of the broader aspectsof my invention.
